The water will maintain this settinguntil the faucet handle is moved. Note that whenthe faucet is set to only cold water, the toe-platefor hot/cold mix will yield only cold water; andwhen the faucet is set to only hot water, the coldwater toe-plate will not dispense any water.

The replaceable color end caps are mounted toyour dental furniture with Phillips head screws.

To remove an end cap, first clear the shelves of theunit to provide easy access to the mounting screwslocated on the interior of your dental furniture(see Figure 4).

Remove the plastic screw caps covering thescrews (located in the uppers and the lower equipment end only) by gripping the cap firmlyand pulling. Then remove the screws, allowingthe end cap to be lifted off the unit.

To replace the end cap, position the end cap overthe screw holes, install the screws. Replace thescrew caps on the equipment end.

PHILLIPS HEAD SCREWS

CautionWhen removing or replacing end caps on lowerunits, you will need someone to support the endcap to prevent it from falling off the unit whenthe screws are removed.

Replacing Color End Caps

You will need a 24 inch, 20 watt replacementtube (order A-dec Part No. 041.261.00 or replacewith #F20T12/CW or equivalent tube).

To replace a burned-out fluorescent light, reach upinto the recessed area above the workspace (seeFigure 5) and carefully twist the tube 45°. Thenlower the tube, tilting it slightly at one end to avoidthe switch wire extending underneath the light.

In operatories with more than one Preference unit, the Master Panel Light Switch (refer to page 5)can be wired to control all Preference task lighting.This allows all lights to be turned on and off at one central location, typically at the 12 O’Clock position. This wiring is usually done when yourdental furniture is installed. Contact your authorized A-dec dealer for more information.

When your equipment is first used, check thesolids collector jar (located under sink) daily todetermine the cleaning intervals appropriate foryour particular practice. Empty the jar whensolids have accumulated to a depth of 1 1⁄2-inchesor more. Even if waste levels are quite low, we recommend cleaning the solids collector at leastonce per week.

To clean the solids collector jar, turn the vacuumsystem ON, then locate the manual drain knob(labeled PULL TO DRAIN) under the sink (see Figure 19 on page 25). Pull this knob and holdit out until the drain stops drawing water. Place apan or towel under the solids collector jar to catchthe small amount of water that will be spilledwhen you unscrew the jar. Remove and clean thejar. Check the gasket to make sure it is securelyseated in the lid, then reinstall the jar. Run waterin the sink, then check carefully for leakagearound the top of the jar before removing the panor towel.

24


Vacuum Drain (optional)

Cleaning

If the sink backs up or makes a continuous gurglingnoise, pull the manual drain knob (labeled PULLTO DRAIN) under the sink (see Figure 19). If thesink does not empty, or if it continues to gurgle,call your authorized A-dec dealer for assistance.If the sink empties when you pull the manualdrain knob, but does not drain (or continues togurgle) under vacuum operation, adjust the vacuum drain actuator as instructed on page 26.

Figure 19. Solids Collector Cleaning

Servicing

To adjust the vacuum drain actuator:

1. Turn the vacuum signal valve adjusting screw(see Figure 20) clockwise until the drain opens.

2. If the drain operates continuously, turn theadjusting screw counterclockwise until itcloses. Do not turn the adjusting screw farenough to release the vacuum signal valvefrom its housing.

3. Alternately run water in the sink and adjustthe vacuum signal valve until the drain operates quietly and keeps the sink empty.

If the sink does not drain, or drains poorly, theremay be an obstruction in the drain assemblyabove the solids collector jar. Call your authorizedA-dec dealer for assistance.

If the preceding steps fail to correct the prob-lem, call your authorized A-dec dealer for recommendations.
